What is the outer product of two vectors
the outer product of two vectors is a matrix where each element is the product of a corresponding element from the first vector with a corresponding element from the second vector. The result of the outer product of two vectors is a matrix where each element is the product of a pair of elements from the two input vectors. If the two vectors have dimensions n and m, then their outer product is an n×m matrix.
for example, Given two vectors a=[a1, a2, a3] and b=[b1, b2, b3] their outer product will be a matrix:
a×b=|a1b1 a1b2 a1b3|
|a2b1 a2b2 a2b3|
|a3b1 a3b2 a3b3|
below are different ways by which we can Calculate the outer product of two vectors:
Calculate the outer product Using outer function
In this approach we will make use The outer function in R which is used to computes the outer product of two arrays or vectors.
in below example we have used outer function to calculate the outer product of two vectors.
# Define two vectors
x <- c(1, 2, 3)
y <- c(4, 5, 6)
# Calculate the outer product
outer_product <- outer(x, y)
print("outer product is: ")
print(outer_product)
